Specification of Letters Patent.

Patented May 11, 1915.

T0 all 'whom t may concern.'

Be it known that I, CHARLES P. STANBON, a citizen of the United States,residing at Saugus, in the county of Essex, Commonwealth ofMassachusetts, have invented an Improvement in Cementing-Vlachines, of

Ywhich the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

My invention relates to machines for cementing boots and shoes and hasreference more particularly to improvements in means for regulating andcontrolling the supply of `cement to the brush, and the regulation andcontrol ofthe application of the cement by the brush to the work.

My invention also comprehends novel means for clearing or cleaning thebrush.

` The above, withv other features of my invention will be moreparticularly disclosed in the following specication.

In the drawings: Figure l is a front elevation of a portion ofthe headof a cementing machine illustrating one embodiment of my invention; Fig.2 is a sidevelevation of the same; Fig. 3 is a cross section'on the line3 3, Fig. 2, showing the brush in section; and, Fig. 4 is a crosssection of the clearer looking from the left on the line 4 4, Fig. 1.

Referring to Fig. 1, the head is indicated at 1, mounted upon which isthe cement can 2, which is shown broken away and provided with a nozzle3, controlled by a suitable valve 4, below which is the cement applying`brush 7, mounted upon a shaft 8, supported in suitable bearings in thehead l, and rotated by any desired means. The said valve 4 is carried atthe end of acurved arm 5, secured to a shaft 6, suitably controlled asby a foot t-readle (not shown) for regulating in a 'general way thesupply of cement flowing from the nozzle 3 upon the brush. The head isadapted to be mounted upon a suitable post or other support, not shown.

rlhe brush 7, as shown, comprises two disks 9 and 10, providedrespectively with laterally extended hubs 11 and 12, These hubs areprovided with inwardly projecting pins 13 vand 14 which enter alongitudinal groove in the brush shaft, so that both ,sec`` tions of thebrush are caused always to rotate in unison with the shaft, but may beseparated more or less on said shaft. The

brush sections are respectively provided with peripheral iianges 15-16in which bristles 17 are mounted, the edges of said flanges beingrecessed or undulated, as shown in Figs. 2 and 3, the undulations of thetwo sections interlocking so as to stagger the groups of bristles andpresent an effective periphery while permitting one section of the brushto be moved toward and from the other section thereof, to vary or adjustthe width of the brush as desired to suit the character of thework to beperformed. The outer section of the brush is moved, by means of a screw18 tapped into the end/of the shaft 8, and opposed by a spring 19 coiledaround the hub of said outer section, and between it and the opposite orinner section.

At one side of the shaft 8 and preferably in the same horizontal planetherewith is an arm 2() provided with apertures 21, 22, to receive thestationary yguide pins 23, 24, eX- tending laterally from the head 1.Between said guide pins is the threaded stud 25, that receives the thumbnut 26, and upon this stud and between the head 1 and the said arm 20 isa coiled spring 27. The pins 23 and 24 serve to keep the arm 20 thereonin proper alinement while` permitting it to be adjusted inward andoutward thereon by the combination of the nut 26 and spring 27. One endof this arm 2O is upturned at 28, and tothis upturned end is screwed theinner anged end of the side wall 29 of a chute in which the cement brushturns. The opposite side wall 30 of the chute is also provided with aflanged member at 30a, the flanges of the two sides lapping one anotherand being adjusted one relative to the other to vary the width of thechute to correspond with the width of the adjustable brush.

rIhe width of the cement chute may be varied in any desired manner.Herein I have made the outer wall 30 adjustable by means of screws 31,and opposing springs 32, see Fig. 3. This chute prevents the cement fromspreading down over the sides of the brush and tends to confine thebrush toits proper width, bringing it back to its proper width wheneverit spreads unduly.

The quantity of cement to be applied to the work is determinedparticularly by the space between the back of the chute and the brush,and this space is regulated, being increased or diminished, by adjustingthe ceive the shank 37 of a guide 38.

arm E20 toward or from the brush by means of the thumb screw 26 and thespring 27 referred to. The cement used upon shoes is generally of athick viscid nature, which is easily controlled in the above manner. Theregulation of the supply of cement as above described results in a largesaving thereof and also avoids staining the sole by surplus cement whichotherwise would be carried to the work by the brush.

Depending from thehead 1, see Fig. 2, is a lug 33, drilled vertically toreceive the post 34 secured therein by the set screw 35. At its-lowerend this post carries a rectangular vhead 36, adjustable vertically onsaid post and drilled horizontally, preferably in the same verticalplane as the post, to rerThis shank is provided with a stop screw 39, toprevent it from being accidentally withdrawn from the block 36, andrests laterally against the post 34, which latter is flattened for thepurpose. One end of the head 3G, see Fig. 1, is tapped to receive ascrew 40, which when set against the guide shank 37, not only clampssaid shank and guide in position, but by contact of said shank with saidpost 34, serves also to clamp the head v36 in adjusted position on itscarrying post 84. The guide 38 enables the workman to easily keep theshoe sole in proper position with respect to the brush.

The head 1 close beside the cement nozzle 3, Fig. 1, is socketed toreceive an adjustable stem 41, of the two part clearer trough 42. Thistrough is made in two parts, Fig. 4, one part, 48, being integral withthe said stem, and the other part 44, adjustable relative thereto, as bya screw 45 and an opposed spring 46. One of said parts, herein the outerpart, is provided with a transverse clearer plate 47, provided at itslower edge with clearing points or teeth 48, which project slightly moreor less into the path of rotation of the bristles of the cement brush.This clearer projects through the opposite or inner side wall of thetrough, so as to permitfthe sides of the trough to be separated more orless and to accommodate the varying widths of the brush, the unusedlength of clearer projecting through and beyond the inner side wall ofthe trough.

It is customary in making many grades of shoes, after'the welt is sewedon to the insole, to cover the lower face of the insole with a layer ofground cork and cement, before the outsole is laid thereon. It is alsocustomary to cover the welt with cement, before the outsolel isattached, and for this purpose the shoe may be passed beneath a brushsimilar to the one shown in the drawings in my application herein. Inthis operation as heretofore conducted, a serious difficulty has beenthe picking up by the brush of small particles of cork which have notadhered to the insole, these being carried'V by the brush up into thechute and, collecting there, gradually forming a sticky mass which hasseriously interfered with the successful flowing of the cement from thenozzle to the brush and the application of the same by the brush to theshoe. Cement delivered from the can 2 through the nozzle 3 collects inthe receptacle formed by the walls 29 and 80 of the chute and theperiphery of the brush and it is in this receptacle that the sticky massreferred to above collects. The comb 48 as clearly shown in Fig. 1 isinclined to the periphery of the brush and is arranged to direct awayfrom this receptacle the material removed from the rotary brush. Myinvention completely avoids this difficulty by providing the clearer 42,which is so adjusted that the points 48 pick off all particles offoreign matter from the bristles and cement, so that when the bristlesreach the cement chute they are substantially free from allobjectionable foreign matter, and are in proper condition to receive anew supply of cement and to apply the same to the shoe. By the abovedescribed device a large amount of cement is saved and such cement as isused is applied to the soleV free from any foreign matter that wouldinterfere with the proper cementing of the work.

It is, of course, obvious that my invention, particularly as to thepickers, is not limited to the precise form here shown, but may bevaried and still accomplish the same result with more or less success.
